Technics SL-1300G

Key Features Coreless direct drive motor achieving stable rotation ΔΣ-Delta Sigma Drive suppresses vibrations from the motor for smoother, more accurate rotation Anti-vibration structure with a three-layer platter and a two-layer chassis Low-noise, low-voltage power circuit and a switching power supply Tonearm achieving high Initial-motion sensitivity High-rigidity body and high-damping silicon insulators for smooth sound and isolation from various vibrations Coreless Direct Drive Motor Achieving Stable Rotation The use of a coreless direct-drive motor with no iron core eliminates uneven rotation of the turntable known as cogging. Also, the twin-rotor construction reduces the bearing load while maintaining high torque and reduces minute vibrations during rotation. Furthermore, the SL-1300G’s motor was redesigned to eliminate subtle vibrations that could affect sound quality. To improve rigidity, the same reinforcement pattern as the Reference Class SL-1000R/SP-10R was used for the coil mounting base. Motor-Drive System, ΔΣ-Drive (Delta Sigma Drive) Unlock a realm of audio precision with the ΔΣ-Drive – a state-of-the-art system harnessing Technics’ expertise in PWM signal processing. In addition to reducing harmonics, the drive suppresses vibrations from the motor for smoother, more accurate rotation, ensuring a rich reproduction of the music. Three-layered Turntable Platter The turntable has a three-layered construction with a rigidly combined brass and aluminium die-cast platter. With a deadening rubber covering its entire rear surface to eliminate unnecessary resonance, thereby achieving high rigidity and vibration damping. This delivers smooth rotational stability and inertial mass surpassing the SP-10MK2, the direct-drive turntable standard used by broadcast stations worldwide, as well as having more than twice the inertial mass of the SL-1200MK5. Two-layered Cabinet Construction The SL-1300G ensures high rigidity by using a body with a two-layered construction that solidly unifies the BMC and the aluminium die-cast chassis. Reinforcing ribs have been added between the motor/tone arm on the top panel. This improves rigidity and vibration damping characteristics. High-level Balance Adjustment When the weight distribution of the turntable is uneven, excess vibration or noise occurs during rotation, which causes degradation in sound quality. Therefore, the balance of the turntable is adjusted at the factory by using specialized high-precision balance adjustment equipment for each and every item after the turntable is assembled. Turntables that have undergone adjustment are labelled with a sticker reading “BALANCED” to indicate that adjustment has been done.
